Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy, Safety, Efficacy

To confirm superiority of once-weekly semaglutide s.c. 2.4 mg versus once-weekly semaglutide s.c. placebo, both as an adjunct to a 52-week blended face-to-face (F2F) and electronic behavioral therapy (eBT) program in treatment-seeking adolescents (12 to <18 years) with obesity on percentage reduction in body weight (% BMI change) [after completion of an initial 8-week blended F2F and electronic LED (eLED)].

Secondary objectives 1

  1. Main secondary objectives: 1. to compare the safety and tolerability of semaglutide s.c. 2.4 mg once-weekly versus semaglutide s.c. placebo as an adjunct to eBT (week 8-60). 2. to compare the effect of semaglutide s.c. 2.4 mg once-weekly versus semaglutide placebo as an adjunct to eBT on a number of measures including body composition, cardiometabolic risk factors and biomarkers, physical activity, sleep, and various patient reported outcomes. 3. to assess the feasibility, safety, and preliminary effectiveness of an 8-week eLED intervention (week 0-7). 4. to assess the feasibility of a 52-week eBT intervention for weight loss maintenance (week 8-60).

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Percentage change in BMI (Time frame: From week 8 to week 60)

Secondary endpoints 1

  1. The main secondary endpoints include the number and severity of adverse events, physical activity, sleep, psychiatric symptoms, eating disorder symptoms, and health-related quality of life.

Description
The participant was dispensed a wrong kit number / Dispensing Unit Number (DUN) at randomisation (week 8, May 7, 2025) which might have resulted in a wrong IMP (placebo or semaglutide) the first 22 weeks of the study. The participant has received the correct IMP from week 30 (second drug dispensing visit) until week 51 (current week),and will be offered to continue with the drug until week 60 (EOT).
Sponsor actions
Corrective: 1. Local PI (Site 2) have arranged a face-to-face meeting with participant and parents and informed about the breach and potential consequences during the first week after becoming aware of the previous breach.
2. Local PI has also invited the family to a new meeting to continue the communication on how to proceed. If the participant/parents want to continue participating in the study taking the correct IMP (since week 30), the participant will continue taking the correct IMP another 9 weeks (until week 60) without unblinding.
3. Further progress will be discussed with the participant/parents until week 64 (end of study).
4. The participant’s data will be flagged for further discussion on how to be used in the analyses with the study statisticians before the final study report.
5. The incident will be documented in the patient record, eCRF and the eTMF

Preventive:
1. The pharmacy argues that their standard operating procedures (SOPs) are appropriate, and that they will not change these procedures despite this incident human error.
2. Although the cause of this breach was related to drug dispensing at the pharmacy, the research staff in eBATLE (all sites) will be reminded about our existing SOP 8 regarding IMPrandomisation, allocation, and drug Dispensing Unit Number. This information will be delivered and discussed at the next ordinary research staff meeting and in the first biweekly meeting with the PIs.

Description
The participant has undergone medical treatment and rehabilitation after hospitalisation (previous SAE probably not related to treatment) after Week 6 in the low-energy-diet phase of the study (Nov 17, 2025). Visit Week 7 was postponed until he had fully recovered and his nutrition status again allowed low energy diet. He has gradually changed changed his diet the last weeks and should be back to almost similar condition as before he became ill; week 6 according to protocol. His body weight is slightly above that registered at Nov 14 (109 kg), recently 112 kg, and he reports feeling fine and is highly motivated to continue participating in the study.
The participant’s data will be flagged for further discussion on how to be used in the analyses with the study statisticians before the final study report.
